Wide Field in Cepheus of the mother nebula of the famous elephant trunk !C1396 and nearby is the bat nebula. I was not able to pull out the squid nebula with the OIII data. I am not sure if I would need to get blue filter data or just a lot more OIII. These are popular targets and I have shot them at longer focal length previously, but I am loving the wide field. You rarely see the full nebulas. Cepheus has some really nice targets. I am really enjoying doing some wide field imaging with my Canon 135mm lens.

Nice image!

Not sure what you mean when you say you weren't able to pull out the squid, it's very clearly there! More OIII data would help to bring out the structure a bit more, but it will always be dim. No need to use a blue filter, it's an emission nebula.
